L'invention concerne une tuile solaire (1), comprenant un cadre de boîtier (20), un module photovoltaïque (40) et une plaque métallique arrière (60) destinée à être fixée à la base, plus particulièrement à une latte de toit (11). Sous le module photovoltaïque (40), une cavité (2) ayant au moins deux ouvertures (3, 4) est formée à l'intérieur du cadre de boîtier (20) de façon à ce que l'air ambiant (U) puisse circuler dans ladite cavité. La tuile solaire (1) est caractérisée en ce que le module photovoltaïque (40) est intégré dans un boîtier de verre (41) et le boîtier de verre (41) est relié de manière fixe au cadre de boîtier (20). L'invention concerne également un procédé de fabrication d'une tuile solaire (1) de ce type.
